DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-10 An embodiment of the present invention discloses a gastrointestinal decompression device for gastrointestinal surgery, which is used to solve the problem that the traditional single-bottle suction can only collect the liquid in the stomach and intestines, but cannot sterilize and filter the sucked gas: Reference Figure 1 , Fig.10 Specifically, the decompression device includes a frame 1 and a lifting frame 2 slidably connected to the frame 1. In the embodiment of the present invention, the frame 1 includes a bottom plate 17 and two guide frames 18 fixed above the bottom plate 17. The lifting frame 2 is slidably connected between the two guide frames 18. A wheel set is also installed below the bottom plate 17. As a preferred embodiment, the wheel set in this embodiment can be set to a universal wheel with a braking function, so as to facilitate the convenient movement of the entire device during use; Reference Figure 2 , Figure 3 A clamping mechanism 3 is slidably connected to both sides of the lifting frame 2, and a container bottle 4 and a sterilizing bottle 5 are respectively installed in the two clamping mechanisms 3. The container bottle 4 is used to connect the drainage tube, and a guide tube 6 is connected between the container bottle 4 and the sterilizing bottle 5; The top end of the disinfection bottle 5 is connected to a pump member 8 via a negative pressure pipe 7 . The pump member 8 is fixed on the frame 1 . A gas purification mechanism 9 is also provided on the pipeline of the negative pressure pipe 7 .

[0021] It should be noted that the disinfection bottle 5 described in this embodiment is filled with disinfectant, and one end of the guide tube 6 is located below the liquid level of the disinfectant in the disinfection bottle 5; During the specific operation, firstly, the upper end of the container bottle 4 is connected to the drainage tube, and the drainage tube is inserted into the patient's body from the oral cavity or nasal cavity, and the pump 8 generates negative pressure, and the negative pressure is connected to the container bottle 4 and the disinfection bottle 5 in turn through the negative pressure tube 7 and the guide tube 6, and the gas and liquid in the patient's intestine are sucked out, and the liquid is stored in the container bottle 4, while the gas continues to move along the guide tube 6 and enters the disinfection bottle 5. Since the disinfection bottle 5 is filled with disinfectant, by ensuring that the gas is fully in contact with the disinfectant, the gas can be disinfected and sterilized. The purpose of this design is to prevent the discharged gas from carrying bacteria, thereby avoiding pollution to the environment; Secondly, when the gas continues to move and be discharged under the negative pressure suction of the pump 8, it will also pass through the above-mentioned air purification mechanism 9, and the air purification mechanism 9 will eliminate the odor in the gas to further ensure the cleanliness of the discharged gas.

[0022] Reference Figure 4 In some embodiments, a platform 11 is fixedly installed on the inner side of the frame 1 of the present invention, a motor 12 is fixedly installed on the bottom of the platform 11, a screw rod 13 passing through the platform 11 is fixedly installed on the shaft end of the motor 12, and a nut seat 14 is installed in the middle of the lifting frame 2, and the screw rod 13 is threadedly connected to the nut seat 14.

[0023] That is, in this embodiment, the motor 12 drives the screw rod 13 to rotate, and the threaded connection driving force of the screw rod 13 and the nut seat 14 is used to control the up and down movement of the entire lifting frame 2, so that the height of the container bottle 4 and the disinfection bottle 5 can be adjusted. The purpose of adopting this height adjustment is to facilitate the medical staff to conveniently disassemble and assemble the container bottle 4 and the disinfection bottle 5 and to meet the height adaptation requirements under different decompression scenarios.

[0024] Reference Figure 5 , Figure 6 , further, the clamping mechanism 3 in this embodiment includes a frame 31 slidably connected to the side of the lifting frame 2, the frame 31 in this embodiment includes a crossbar part and a vertical rod part, the vertical rod part is fixed to the front side of the crossbar part, wherein the crossbar part slides with the lifting frame 2, and a bearing portion 32 and abutting portion 33 are provided at the front end of the frame 31, the bearing portion 32 is arranged at the bottom of the frame 31, and is used to bear the bottom of the container bottle 4 and the sterilizing bottle 5, and of course the abutting portion 33 is used to stop the rear side of the container bottle 4 and the sterilizing bottle 5, and preferably, an arc groove matching the shape of the container bottle 4 and the sterilizing bottle 5 is provided on the end surface of the abutting portion 33 in this embodiment; A splint assembly 34 is movably connected to the front end of the frame 31, and a driving assembly 35 for driving the splint assembly 34 to move is provided inside the frame 31. That is to say, in this embodiment, the container bottle 4 and the disinfection bottle 5 are clamped and fixed by means of the splint assembly 34 to achieve installation of the container bottle 4 and the disinfection bottle 5. This makes it convenient for subsequent medical staff to disassemble the container bottle 4 and the disinfection bottle 5 so as to discharge and clean the accumulated liquid and disinfectant in the interior in turn. This ensures the stability of each bottle component during the decompression operation and improves the convenience of subsequent maintenance.

[0025] Reference Figure 7On the basis of the above-mentioned embodiment, the clamping plate assembly 34 of the present invention comprises a U-shaped rod 341 connected to the frame 31, and a clamping plate 342 is fixedly connected between the two ends of the U-shaped rod 341. Of course, an arc-shaped portion may also be provided in the middle of the clamping plate 342 described in the present embodiment, and the clamping plate 342 is opposite to the abutting portion 33 to form a clamping space. When the container bottle 4 and the sterilizing bottle 5 are installed, the corresponding bottle is first placed on the bearing portion 32, and then the clamping plate 342 and the abutting portion 33 can be relatively moved to clamp and fix the bottle. The arcs on the opposite surfaces of the clamping plate 342 and the abutting portion 33 can realize the adaptation of the container bottle 4 and the sterilizing bottle 5 to improve the fixing stability of the bottle. Of course, in order to achieve elastic clamping force on the splint 342, a spring 343 is fixedly connected between the U-shaped rod 341 and the frame 31 in the present invention. The spring 342 described in this embodiment can be set to two, which are respectively connected to both sides of the U-shaped rod 341.

[0026] Reference Figure 8 Furthermore, the driving assembly 35 of the present invention includes a shaft 351 rotatably connected to the inner side of the frame 31 , and at least one wheel 352 is fixedly mounted on the outer side of the shaft 351 ; An eccentric rod 353 is fixedly installed on the outer side of the shaft rod 351, and a connecting rod 354 is pin-connected between the end of the eccentric rod 353 and the U-shaped rod 341; A vertical plate 355 is provided on the end surface of the carrier 11 for guiding the wheel 352 to rotate.

[0027] Specifically, in this embodiment, two wheel members 352 are fixedly mounted on each of the shaft rods 351, and two eccentric rods 353 are also provided to synchronously push the two sides of the U-shaped rod 341 to ensure the sliding stability of the U-shaped rod 341. When the decompression operation is completed, the entire lifting frame 2 can be driven downward by the motor 12. When the lifting frame 2 moves down to a predetermined position, the wheel member 352 contacts the vertical plate 355, and the entire wheel member 352 starts to rotate under the action of friction, thereby driving the entire shaft rod 35 1 is rotated, and when the shaft rod 351 rotates, the eccentric rod 353 is driven to rotate. Since the two ends of the connecting rod 354 are pin-connected with the eccentric rod 353 and the U-shaped rod 341 respectively, when the shaft rod 351 rotates, the entire U-shaped rod 341 is driven to move outward, thereby achieving the purpose of driving the clamping plate 342 to automatically move outward and unlock, that is, in this state, the clamping plate 342 is free to break away from the clamping of the bottle part, and is used to open the corresponding bottle cap through the thread, thereby realizing the convenient disassembly of the container bottle 4 and the disinfection bottle 5, and improving the convenience of disassembly.

[0028] During installation, the container bottle 4 and the sterilizing bottle 5 can be directly placed on the bearing part 32 and after the pipelines are connected, the bottle parts can be automatically clamped when the lifting frame 2 rises, without manual intervention to optimize the convenience of the operation.

[0029] Of course, in other embodiments, the wheel member 352 may be configured as a gear, and the vertical plate 355 may be configured as a gear plate, so as to ensure the stable rotation drive of the shaft 351 by means of the stable meshing force between the gear and the rack plate.

[0030] Reference Figure 3 In some embodiments, the screw rod 13 of the present invention includes a threaded portion 131 and a smooth portion 132, and the smooth portion 132 is disposed at the bottom of the screw rod 13; Reference Figure 8 The nut seat 14 is movably plugged with the lifting frame 2 and circumferentially locked. As a preferred embodiment, a protrusion is provided on the outer side of the nut seat 14, and a notch is provided in the slot of the lifting frame 2. The circumferential locking ability of the nut seat 14 and the lifting frame 2 is ensured by the guiding cooperation between the protrusion and the notch; A stopper 15 is formed at both ends of the nut seat 14, and the two stoppers 15 are respectively arranged on both sides of the lifting frame 2 to limit the up and down movement position of the nut seat 14 to prevent it from slipping from the inside of the lifting frame 2. An elastic component 16 that abuts against the nut seat 14 is arranged above the carrier 11. The elastic component 16 is used to push the nut seat 14 in the reverse direction, so that when the nut seat 14 moves to the smooth portion 132, a reverse thrust is provided to enable it to engage with the threaded portion 131 here when the screw rod 13 is reversed.

[0031] Reference Fig. 9 Preferably, the elastic component 16 in the embodiment includes an elastic sleeve 161 fixed above the carrier 11, and a compression spring 162 is placed on the inner side of the elastic sleeve 161. The elastic sleeve 161 and the compression spring 162 are sleeved on the outer side of the screw rod 13. Specifically, the elastic sleeve 161 in this embodiment is configured as a silicone sleeve, and the compression spring 162 is embedded in the inner side of the silicone sleeve. The compression spring 162 is protected by the silicone sleeve to improve its durability.

[0032] That is to say, in this embodiment, when the motor 12 drives the lifting frame 2 to move downward, in order to control the moving stroke to ensure that the lifting frame 2 does not collide with the carrier 11 when the clamping plate 342 is unlocked, a smooth portion 132 is provided at the bottom of the screw rod 13. When the nut seat 14 drives the lifting frame 2 to move downward, the lifting frame 2 drives the two clamping mechanisms 3 to move downward. When the wheel member 352 contacts the vertical plate 355, the shaft rod 351, the eccentric rod 353 and the connecting rod 354 drive the U-shaped rod 341 to move. At this time, the clamping plate 342 is in an unlocked state. At the same time, the nut seat 14 continues to move downward and slides onto the smooth portion 132 of the screw rod 13. Since the screw rod 13 and the nut seat 14 do not generate meshing force at the smooth portion 132, the nut seat 14 cannot continue to drive the lifting frame 2 to move downward, so as to form a travel limit point at the smooth portion 132. In addition, the nut seat 14 contacts the elastic sleeve 161 at this position and compresses the compression spring 162, so that the nut seat 14 receives a reverse thrust. When the container bottle 4 and the disinfection bottle 5 are disassembled and cleaned, the container bottle 4 and the disinfection bottle 5 can be placed in the corresponding clamping mechanism 3 again, and then the motor 12 drives the screw rod 13 to reverse. Under the action of the above-mentioned reverse thrust, the nut seat 14 has an upward movement trend until it engages with the threaded portion 131 here. Therefore, after the nut seat 14 and the screw rod 13 are engaged, it drives the entire lifting frame 2 to move upward. At the same time, the shaft rod 351 is reversed under the action of the wheel part 352 until the wheel part 352 and the vertical plate 355 are completely separated. At this time, the clamping plate 342 clamps and fixes the container bottle 4 and the disinfection bottle 5, thereby completing the free unlocking and automatic clamping operation of the container bottle 4 and the disinfection bottle 5, which greatly improves the convenience of disassembling the container bottle 4 and the disinfection bottle 5.

[0033] Reference Figure 5 In some embodiments, the air purification mechanism 9 in the present invention is fixed on the side of the frame 31. Specifically, the air purification mechanism 9 in the present invention includes a filter cartridge 91 fixed to the side of the frame 31 through a bracket, the top of the filter cartridge 91 is connected to one end of the negative pressure pipe 7, and an activated carbon net 92 is filled on the inner side of the filter cartridge 91. The bottom of the filter cartridge 91 is threadedly connected to a bottom cover 93, and the bottom cover 93 is connected to the other end of the broken end of the negative pressure pipe 7.

[0034] That is, in the actual operation process, when the pump 8 generates negative pressure, the gas in the body will first be sterilized and disinfected by the disinfectant in the disinfection bottle 5, and then the gas will further move into the interior of the filter cartridge 91. Since the filter cartridge 91 is filled with an activated carbon mesh 92, the gas can be purified under the filtration of the activated carbon mesh 92 to ensure the cleanliness of the gas discharged from the pump 8, thereby effectively inhibiting the spread of bacteria and ensuring the air cleanliness of the working environment. In addition, in the present invention, a threaded bottom cover 93 is used at the bottom of the filter cartridge 91 to facilitate replacement of the internal activated carbon mesh 92.

[0035] It should be noted that in the above-described embodiments, both ends of the broken end of the negative pressure tube 7 can be connected to the filter cartridge 91 and the bottom cover 93 by means of quick-release connectors. Of course, a bottle cap can be threadedly connected to the bottle mouth of the container bottle 4 and the disinfection bottle 5, and the bottle cap can also be conveniently connected to the corresponding pipe by means of a quick-release connector.

[0036] Furthermore, the guide tube 6 and the negative pressure tube 7 described in the present invention can both be spring tubes, so as to adapt to the position and stroke changes of each mechanism during operation in a specific operation.

[0037] In summary, the present invention adopts a liftable container bottle 4 and a disinfection bottle 5, which can adapt to the height requirements of different users' decompression scenarios during the decompression operation, and at the same time improves the convenience of subsequent disassembly and assembly of the container bottle 4 and the disinfection bottle 5 to optimize the convenience and reliability of the decompression operation. Secondly, the present invention ensures that the gas and the disinfectant are in full contact with each other through the design of an external disinfection bottle 5 and an air purification mechanism 9, and can disinfect and sterilize the gas. The air purification mechanism 9 then eliminates the odor in the gas to further ensure the cleanliness of the exhaust gas, thereby effectively inhibiting the spread of bacteria and ensuring the air cleanliness of the working environment.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
